[SAPHO syndrome].

We report two cases, one 23 and one 27 year old man, with several years background of sternal and sternoclavicular joints pain, respectively. The laboratory tests were normal. Based on the clinical, radiologic and scintigraphic findings, SAPHO syndrome was diagnosed. Bone scintigraphy makes it possible to obtain a whole body scan in a single whole body scan, and can be used for differential diagnosis of other osteoarticular diseases and for evolutive control and therapeutic response.

[99mTc-labelled antigranulocyte anibody fragment Fab scintigraphy (sulesomab, leukoscan) and three-phase bone scintigraphy in the study of painful hip and knee prosthesis].

We aim to assess the diagnostic utility of the combination of a three phase bone scintigraphy (3FBS) and scintigraphy with Fab'antigranulocyte fragments-99mTc (Sulesomab, Leukoscan) in patients with painful joint replacements. We studied 29 patients (22 women and 7 men with mean age 64 years) with knee (15) and hip (14) prosthesis. Scintigraphy was performed with a Siemens Orbiter 75 gammacamera with all purpose collimator. 3FBS was performed as usual with 740 MBq of MDP-99mTc. Sulesomab images were obtained at 1 and 4 hours following injection of 740 MBq, with 300,000 cts per view (knee) and 500,000 cts per view (hip). Both scintigraphic studies were interpreted visually by two nuclear medicine physicians with a 0, 1, 2, 3 score corresponding to normal or mild, moderate or intense hyperactivity respectively. Interpretation criteria for bone infection was Sulesomab uptake grade 2 or 3 in a moderate or large sized area, with congruent hyperactivity on the bone scan. Grade 1 uptake with Sulesomab was considered nonspecific associated to nonseptic conditions. The frequent pattern of uptake in synovial femoral tissue (cap shape sign) in knee prosthesis was considered nonspecific. Diagnostic confirmation procedures were surgery and culture (9) and follow-up (20). All six septic joints were correctly identified. A false positive result was obtained in a case of mechanical loosening in the knee. Negative studies were very helpful in the exclusion of infection. Our conclusion is that sensitivity is high, 100%, and that a normal or grade 1 Sulesomab image makes the presence of infection improbable.

[Early alteration of adrenergic cardiac function in parkinsonisms with Lewy bodies].

BACKGROUND: 123I-metaiodobenzylguanidine (123I-MIBG) myocardial scintigraphy is clinically used to estimate myocardial sympathetic damage in some forms of heart disease, autonomic nerve disturbance in diabetic neuropathy, and disturbance of the autonomic nervous system in neurodegenerative disease. In the present study, examinations were performed to clarify the rate and characteristics of cardiac sympathetic disturbance in Parkinson's disease (PD) and usefulness of 123I-MIBG myocardial scintigraphy to differentiate PD from the Lewy Body Disease (LBD). MATERIAL AND METHODS: 108 subjects were studied. There were 70 patients with PD, 21 patients with LBD, and 17 age-matched normal subjects without neurological disease. The clinical parameters evaluated were severity of the process (measured by Hoehn and Yahr Scale), vegetative manifestations, development time and use of medication taken. Myocardial adrenergic function was analyzed by imaging with 123I-MIBG. Early (15 min) and delayed (4 h) images of the thorax in the anterior view were obtained after injection of 123I-MIBG (111 MBq). The qualitative and semiquantitative 123I-MIBG uptake was quantified by calculating a heart-to-mediastinum ratio (HMR) and analyzed in a blind manner. RESULTS: The mean H/M ratio in patients with PD and LBD was significantly lower than in controls (p < 0.05). This is independent of development time, process severity, use of medication or vegetative manifestations. The HMR obtained in LBD patients is less clear than in PD. CONCLUSION: 123I-MIBG myocardial scintigraphy might detect early disturbances of the sympathetic nervous system in PD and LBD.
